ERT - Ensemble based Reservoir Tool - is designed for running ensembles of dynamical models such as reservoir models, in order to do sensitivity analysis and data assimilation. ERT supports data assimilation using the Ensemble Smoother (ES), Ensemble Smoother with Multiple Data Assimilation (ES-MDA) and Iterative Ensemble Smoother (IES).

`default` current case is empty after running ES #5586

Closed dafeda closed 1 year ago

dafeda commented 1 year ago

Describe the bug After a run of ES (I tried drogon) we end up with 3 cases; default, default_prior and default_smoother_update. default is empty.

To reproduce Steps to reproduce the behaviour:

  1. source bleeding
  2. run ES on drogon_ahm.ert

Expected behaviour Only two cases, one with the prior and one with the posterior. Consider https://github.com/equinor/ert/issues/4160 as well

I think this is intended behaviour. ERT 5 creates an empty default case to mimic behaviour from ERT <5.

I agree it's stupid and we shouldn't have it, but I think that is an issue for another milestone.

Will close this now then, we all agree we should review this behavior, but for now the old behavior is ok.
